Final answer:
To price a double liquor drink, you need to double the standard serving size and account for the higher volume and mass. The liquor's cost, potentially > 1,000x that of a basic alternative, along with a typical 10-15% markup, will influence the final price, which can approach or exceed $1,000 for premium liquors.
Step-by-step explanation:
When pricing a liquor drink, especially for a double, you need to consider several factors. A standard drinking glass for a liquor drink may hold about 1.5 ounces for a single shot. For a double, you would double this amount. When determining the price, you have to account for the increased volume and mass of liquor, which could be a few dozen times more in volume and about 10² in mass compared to a single serving.
The cost of the liquor itself will influence the price of the drink significantly. If the liquor is > 1,000x more expensive than a basic alternative, that will be reflected in the drink's price. Moreover, if providing a double of a very expensive liquor, the total cost for the drink could approach or even exceed $1,000.
Additionally, most establishments add a markup percentage to the cost of the ingredients to arrive at the final price; this could be between 10-15%. This margin covers not only the cost of the liquor but also operational expenses like wages, utilities, rent, etc. Thus, it's not just the cost of the liquor you need to consider but also the overall cost of doing business when pricing a double liquor drink.
